Bully for Scott Hahn. I repeat my question:
Do you accept that sincere, intellectually curious and honest people can arrive at a different conclusion?
Do you believe that anyone who leaves the Roman Catholic Church after careful consideration, much prayer, intense study of Scripture and history can also be "sincere", "intellectually curious" and "honest"? I can give you a list of intellectuals, theologians and others who did just that - left Catholicism and became Evangelical Protestants - if you are interested in reading their stories.
I would be happy to read any of the converts you speak of that have as much between their ears as Scott Hahn. Since he was a protestant theologian who became a Catholic theologian, and has basically memorized the Old and New Testaments and speaks fluent Latin and Greek.
